Allocation Areas
How Will Allocations be Met?
• DC Water– Major investment at Blue Plains (ENR)– Clean Rivers Program, formerly LTCP
• MS4 Permit• Stormwater Regulations• Federal Agency Partnerships
MS4 Permit
• Final MS4 permit issued in Oct. 2011– Requires stormwater regulations with a 1.2 inch
retention standard for new or re-development
– Requires specific practices to be installed :• Trees (4,150 net plantings per yr)• Green Roofs (350,000 SF over 5 yrs)• Impervious Surface Retrofits (18 Mil SF over 5 yrs)
MS4 Permit Cost Impacts
New stormwater regulations will be driver to achieve metrics– Only impacts new and redevelopment projects– Drafted to achieve environmental benefit while
maximizing flexibility for regulated sites. Off-site mitigation and/or fee-in-lieu with a baseline on-
site retention– Consultant analysis determined regulations would result
in a small incremental cost increase for development projects
– DDOE experience demonstrating similar results– Smart Growth study finds that storwmater regulations
are not a driving factor influencing redevelopment
Federal Partnership
• Information submitted by 10 Federal Agencies!– Partnering approach works to improve water quality and
control stormwater runoff• Agencies accepted/acknowledged DDOE assigned target
load allocations for N, P, TSS• All deliverable deadlines were met by Federal Partners• Information submitted includes:
– Narrative about the agencies – Narratives about proposed actions and goals– 2012-13 Two Year Milestones

2012-13 Two Year MilestonesFederal Partners
• Agencies catalogued existing installed BMPs
• Practices to be installed through 2013 were submitted by agencies
• Long-term (programmatic) practices were submitted by agencies– Such as: managing areas as fields, allowing
reforestation, removing permeable areas, developing sustainability, pollution prevention and LID policies
2012-13 Two Year MilestonesDDOE
• Expand urban tree canopy– Plant 4,150 trees per year
• RiverSmart Homes/Schools/Rooftops– ~ 2,000 Homes audited– 4 Schools– 140,000 sq ft of green roof to be installed
• RiverSmart Washington Demo project– Retrofit 22 acres with LID to max extent practical
• Stream Restoration– 7800 ft of stream to be restored
BMP Inspection and Maintenance
• All BMPs need to be inspected and maintained in order to:
– Protect monetary investment– Ensure performance– Maintenance is mandatory
• DDOE inspects BMPs submitted through soil and erosion regulations for
installation, completion, and maintenance– Practices that have gone through the DDOE process are
put on an inspection and maintenance schedule
Tracking and Reporting
• Open communication• Strict observance of reporting periods• Short term goal = Development of a
spreadsheet which could be used by all agencies for reporting
• Long term goal = Central interactive reporting tool (to be developed by EPA per 7/6/11 two year milestone guidance)
What’s Next?
• Final WIP due to EPA March 30th
• Promulgation and implementation of stormwater regs• MOU with Federal Agencies• Ongoing Inspection and Maintenance of all existing
BMPs in the District• Tracking and Reporting on implementation……
– Yearly progress – Two year milestones
• Explore utilizing new and emerging practices and technologies
• Thank you for ‘partnering’ to help us all achieve a clean Chesapeake Bay!
